DAM, WISCONSIN on swanmen This invention relates to improvements in stalls or stanchions of the type employed to hold the heads of cattle while they are operating mechanism, is positioned above the top rail of the stalls, and this not only adds to the height of the structure, but necessitates the use of special bearings for the sliding bar,

. positioned above-said top rail. As the top rail is supported by vertical posts, I have devised arconstruction by which the sliding bar may not only be arranged beneath the top rail, but may be guided by the clamps which connect the posts 'to the top rail, andin these clamps, protected anti-friction bearings may" be arranged for the actuating bar, the construction being such as to prevent hay, chafi' or the like from entering the clamps and operation of the roller bearings. j

Therefore, one Of the objects of the present invention is to provide a stall of this char:

actor, in which certain of the clamps not only" join the top rail to the vertical posts, but also function as anti-friction guides for the actuating rod of the stanchions.

Another object is to furnish a structure of this type in which the hinged members of the stanchions are connected to the sliding operating bar by means of novel latches, so

that one or more cows may be held by their stanchions while the other cows are released, and vice versa.

A further object is to provide in such a mechanism, special latches for positively securing the hinged members of the stanchions to the fixed members of the latter, so that any one of said hinged members 5 may be locked in closed position when desired.

With the foregoing objects outlined and with other objects in view which will appear as the description proceeds, the invention consists in the novel features hereinafter described in detail, illustrated in the accorn- Applicat on fil d. Marsh 5,

Fig. "6' is a front elevation of one of the latch'devcices. i 7 is a horizontal sectional view on the line 77 of Fig. 4;. In thed' awings, lOdesignates the foundation beam of the stalls in whichthe-lower ends of the vertical posts 11 are mounted; these posts being additionally supported-by means of the usual partition pipes 12. I Arranged at the tops of the posts, and supthe latter arefspecial clamps 13, each preferably'consisting of a pair of plates or special castings 14 and 15, (Figs, 2 and; 3) secured together by'any suitable fasteningmeans such as bolts 16, 17, 1 8, 19 and 20." Vertically disposed semi-circular recesses in the lower ends of the plates, provide cylindrical bores to receive the cylindrical upper ends of the posts 11, and the bolts 16 aii'd'l'? function to "firmly secure the clamp to the upper ends of the posts.

The clamp plates are also provided with horizontally disposed semi-cylindrical re cesses which provide a horizontal bore to re- 7 ceive the top rail 21 of the stalls, and the bolts 19 and 20 act to firmly secure the clamp to the top rail. v Intermediate the ends of the clamp plates, other horizontally disposed semi-cylindrieal recesses are provided which form a horizontal bore 22 that serves as a guide for the sliding operating rod 23, andtopermitthe rod to slide without f fietion, a grooved roller 24: is '3 rotatably mounted in the'elamp'onthe bolt 18. Atthis point it will be noted that' the roller is positioned midwaybetween the side 1 i the top rail between Obviously,'when the lever able members is provided witha bracket or otally mounted;

edges of the clamp, so that it-is spaced some distance from the ends of the bore 22, and this arrangement will act toprevent any hay, chaff or the like from working itself into the clamp and interfering with the rotation of the roller. r e I Swivel supports are securely clamped to guide bores in these swivel supports; a a 1 'An -actuating handle26 for the sliding bar is pivotally mounted upon the bolt 18 of one of the special clamps, and its intermediate portion is pivotally connected at 27 to one end of a pltman otally connected 28,- whose other end is pivat 29 to the. sliding bar 23. is swung on its pivot 18, the sliding bar will be shifted in one direction or the other.

Movable sure stop'rods 30 are pivotally connected at 31 to the sliding bar, and their lower ends engage eyes inbrackets-32 which are secured on the posts 11. In actual practice, stationary sure stop rods 33 are also mounted on these posts. i

The fixed members 34 suspended by swivels 35 from the swivel supports25, and theyare joined by chains 36 to the foundation beam, whilethe movable members37 of the stanchionsare pivotally connected to the fixed members by means of hinges 38. The upper end of each of the movslides along the horizontal fixed member, and each of extending swivel 39 which portion 40 of the these swivelshas an upwardly finger 41 that is latched to a special latch 42 and provided with a head'41 f This latch (Figs. 4'to7 inclusive), also preferably consists of a pairof clamp plates 43 and 44 having horizontal recesses forming a horizontal bore to receive the latch plates are clamped to the sliding bar by any suitable means, such as bolts 45 and 46. If desired, the plates may have ex tensions to form a guide 47 to slidably engage the top railof the stalls. 1

One of the clamp plates is provided with laterally projecting ears 49 which carry a piviot pin 50 on which an angular fork 51 is pivthis fork having tin es 52 that are adapted to prevent forward or backward movement of the finger 41. The clampplates have depending lugs 53 which prohibit lateral 553movement ofthe finger 41 and prevent dropping of the head 41*; and when thelatch is secured opposite sides of the lugs 58, so that the tines andlugs provide a 'boxor enclosure to re- When the-latch is closed, it

is held in this.pos 1tion by a sliding keeper 55, which has a verticallydisposed-slot 56' tore'ceive one ofthelbolts of the clamp, and;

betweenthehead of this bolt and the keeper,

Za-washer 57 is arranged, so asto prevent the position (Fig. 5),

the special clamps 13, j and the sliding bar 23 also slides through member of the stanchion,

of the stanchions are the sliding bar 23, and

to the to the finger41, the tines pass along keeper from disengaging its guide boss. A lug 59 on the keeper serves as a finger-piece to permit the operator to actuate the keeper, and also cooperates with a bar 60 of the latching fork, so as to hold the tines in inoperative when the finger 41 of the swivel is to be disconnected from the latch. At such a time, a pivoted latch 61, (Fig. 1), mounted at the upper end of the movable can be engaged with a projecting pin" '62 on the stationary member of the stanchion so as to lock the stanchion against opening.

c From the foregoing it will be seen that invention enables thefslidable actuating bar 23 to be arranged below thetoprail of the stall, andtobe guided by couple the supporting post to the top rail. Furthermore, my construction'allows any one of the-movable members of the stanchions to be latched to, tuating bar, so that one or more of the cows f may-be retained by their stanchions, .while the remainder of the cows are released by the actuation of a common hand control.

NVhile I have disclosedwhat I now consider to be a preferred embodiment of the invention in such manner that the same may be readily understood by those skilled in] the art, I 'am aware that changes may be made in the details disclosed without departing from the spirit of the invention, claims. j v
